I have a Chicago Coin Galaxy shuffle bowler. I’ve had the machine a little over a year. I purchased it from flea market and it was in pieces.
I got it together and working for the most part. The only issue it currently has is that the #3 pin doesn’t score. So it’s impossible to get a strike or a spare.
It goes up like it should. But doesn’t score.
I’ve noticed that the switch stack on the main bank that’s marked for that pin never moves like the rest of them. I’ve cleaned the contacts on that stack, the ones above the pin and below.
I haven’t been able to get a schematic for this unit.
Thoughts?

Here’s a video.

The relay on the back bank? It does not. But neither do any of the other pins.

Ok! What exactly is a “M/B”?

Ohhh I know what a make break is. For whatever reason m/b just wasn’t registering in my brain.
